If the numbers aren't staggering enough, the regulation of these imports sounds like a losing battle, since violations abound. In the Bay Area, according to the report, there are only four wildlife inspectors who only have time to inspect 50 percent of trophies shipped back to the states through that region.

In the past five years, there have been 2,963 documented violations in the U.S. - such as hidden trophies, or skins rolled up in other skins - and a majority of the violations (54 percent) related to the Endangered Species Act. Because of spotty oversight of U.S. trophy hunting imports, poachers can take advantage of the system to bring back carcasses and sell them on the black market.
